María de la Soledad Vicente Solís Lasso de Vega, VII Countess of Fernán Núñez (María de la Soledad Vicente Solís Lasso de Vega, VII condesa de Fernán Núñez)

Doña María de la Soledad Vicenta Solís Lasso de la Vega was born in 1780 and married the VII Duke of Fernán Núñez, whom Goya also painted in a portrait that forms a pair with this one. Following the death of her husband in 1822, she remarried to Filiberto Mahí Romoy, living in Paris until her death in 1840.

The composition, in which the subject appears seated outdoors, is very similar to that employed in the portrait of Joaquina Candado. The sitter, who was twenty-three years old when Goya painted this portrait, is shown wearing a black dress with yellow neckline and sleeves, and a mantilla decorated with exotic red feathers. In her right hand she holds a fan, whilst her left hand is hidden behind her hip. Hanging from her neck is a cameo with the image of her husband. She wears two large earrings that match the ring she wears on her little finger. The position of the sitter's legs has often been criticised as being quite unfortunate for a lady of high-society. Francisco Calvo Serraller states that this posture suggests that Goya did not paint her outdoors but rather in the studio, seated on a chair.

There is a notable difference in technique between the more precise brushstrokes used in the figure of the lady and those of the landscape, which are far more sweeping and broad.
